ideal HE24 HE30 HE35 - no hot water, heating yes, Error h6

[jeff_porter]

Forgive my innocents.

But what is the DV ?

Also, how do I find a Ideal boiler to come out and have a look?
Does anyone have a contact number?

 

[jeff_porter]

ok. I'm learning as I go.

Spoke to Ideal and H6 is 'reset button is stuck in'.
So I'll check that out tonight.

As I said in a previous reply, although my manual states it as a b which is why I questioned the 6.

DV = diverter valve, very prone to faulting on these boilers.

I had a call to an isar he 30 today, which was displaying the fault code H E flashing on and off. When i looked in the manuel it wasn't listed. So before i took the cover off i phoned there tachnical help. And after 10 mins finally got through and was told that that was the pump...

Checked the pump which was spinning. So then thought the impellor had come off... After stripping the pump and finding everything was ok i phoned technical help. They then said that there must be a blockage in the or air lock in the radiator circuit (but definately not the boiler).

At this piont i decided to ignore the technical help and found that the heating flow thermistor had a resistance of 0.5K ohms which should about 10K. and after replacing hay presto boiler working perfect.

So much for tachnical help from ideal.....................

I've checked the reset switch, and although it doesn't feel like positive yes/no when I push the button, it doesn't seem stuck.

I've taken a load of pics.

Its a HE24

the out side...

the outside: system off.

The internals (I've not touched anything, just taken the pics)

Next turning on of the power.
(now it does make strange noises for a bit when turning it on)

Next turning the hot water tap...
No idea what the error code HA means. Again its not in the book.

Video clip of me turning on the boiler.
Notice the sound like Im in the engine room of the Titanic

I didn't get the error code of H6 this time.

but the CH out pipe pressure raises from 0 to 1/2 a bar.

Think its time to call out the boiler guy.

 

[Gasguru]

Try sticking some water in it!

The pressure gauge is near zero - it should be about 1 to 1.5 bar when the system is cold and off. The filling loop valves underneath.

 

[gas4you]

A is overheat. H means its a serious fault. Down to lack of water in the boiler. Pity you didn't mention this earlier.

 

[jeff_porter]

ok.

so how do I do that? put water in it? (system is off at the mo)

These are the pipes at the bottom...

 

[gas4you]

Somewhere under the boiler usually there will be a flexible silver braided short pipe from the cold mains to the return ch pipe. often it will have 2 washing machine type valves on it or valves that can be turned with a small flat bladed screwdriver.

 

[Gasguru]

Further down the pipes on the left is a stainless braided hose. Open the black valve (at one end of the hose) slowly and bring the pressure up to 1 bar then shut off the valve.

 

[jeff_porter]

ha ha.

Like my dad says "stand back boy, you can't see the wood for the trees"

So I've turned the black valve and increased the pressure to 1.5bar.

gonna turn it on now to see what happends.

 

[jeff_porter]

Jeff runs over to 'gas4you' and give me a big hug

yea! I have hot water again! I not longer have to smell like a dead badger.

Ok, two final questions...


1: how did this happen to start with?

2: when is it best to bleed the rads? when the system is A: on at the main, but off at the unit, B: on at main and unit, C: when the heating system is running and rads are hot?

Thanks again, can't tell how much I owe you!!

 

[gas4you]

Oh no they all think I'm G4Y already

Bleed rads when cold and system off.

Just hope you haven't done any damage to boiler.

No water could have occured gradually or prv opened because of another fault.

Have you noticed any leaks/damp patches anywhere?

 

[jeff_porter]

>>No water could have occured gradually or prv opened because of another fault.

prv?
"water could have occured gradually" hu ?

>>Have you noticed any leaks/damp patches anywhere?
Nope. a few drops of water under one of the rad in the spare bedroom.
but its only a very small stain in the carpet. not a damp patch.

>>damage.
no error codes came up, and the heating in the flat has been off the past two weeks. Since noticing the problem we've not used much hot water.
(been using the electric show in the other room). Noticed the problem 7 days ago if that.
So hoping no damage has been done.

 

[gas4you]

PRV = pressure relief valve, 15mm pipe that terminates outside up the wall just below boiler height usually.

A few drips a day somewhere would over time lead to zero pressure in the system and as you hadn't noticed it was at zero I doubt you would have noticed it was slowly losing pressure!
